A Russian submarine has been intercepted by the Royal Navy as it cruised towards the English Channel.

The sub is being escorted by frigate HMS Kent and is expected to pass the Strait of Dover on Wednesday morning.

It is understood the Stary Oskol, a Kilo-class submarine capable of carrying cruise missiles and torpedoes, was first detected in the North Sea where Nato forces are monitoring the waters.

Locating this submarine was a combined effort with Nato allies and shadowing such units is routine activity for the Royal Navy.
We continue to escort the submarine as it conducts its passage, providing a visible presence.

– HMS Kent's Commanding Officer, Commander Daniel Thomas

Defence Secretary Michael Fallon said: "This shows that the Navy is maintaining a vigilant watch in international and territorial waters to keep Britain safe and protect us from potential threats."
